The present invention is a system and method for detecting and analyzing motion patterns of individuals present at a multimedia computer terminal from a stream of video frames generated by a video camera and the method of providing visual feedback of the extracted information to aid the interaction process between a user and the system. The method allows multiple people to be present in front of the computer terminal and yet allow one active user to make selections on the computer display. Thus the invention can be used as method for contact-free human-computer interaction in a public place, where the computer terminal can be positioned in a variety of configurations including behind a transparent glass window or at a height or location where the user cannot touch the terminal physically.

The method also includes initiating a second communication session with the caller. The second communication session comprises a feedback session parallel to the first communication session. The method also includes receiving from the caller feedback relating to the first communication session between the caller and the first agent.

A haptic display includes at least one haptic device that can give tactile feedback instead of visible feedback. Each of the haptic devices converts a signal from a signal producing unit into force or tactile pattern. The haptic device does not require a large mass, so that it can be provided on almost any portion or part within the body of a mobile apparatus. For example, the haptic device can be embedded under a touch panel display that constitutes both input and output device. By providing the haptic devices under respective menu/function button areas displayed on the touch panel display, it is possible to stimulate the specific button in response to the user-input-operation, thereby directly providing the tactile feedback to the user's finger touching the corresponding button.

A method and system for creating an object or character in a drawing window and simultaneously displaying the object or character in animated form wherein the animated form is available for instant playback or feedback to the user is described. A single process is used for creating the object and animating the object. The user is able to draw the object in a drawing window and have the object animated in an animation window as the object is being drawn, thereby allowing the user to immediately see the results of the animation. A single process is used to create the object or character (i.e., the “drawing” stage) and to display the object in animated form. The drawing and animation can be shown side-by-side for the user thereby enabling the user to see the animation of a character that the user had created moments before. The animation can take place in an animation window or be placed in a pre-existing context, such as an ongoing story line or a collaborative community context created by multiple users.

The invention discloses a high-pressure self-oscillation oscillating impulse jet flow nozzle with continuous adjustable cavity length. The high-pressure self-oscillation oscillating impulse jet flow nozzle comprises an inlet nozzle, an adjusting ring, a base and an outlet nozzle, wherein the base is an inner hollow cylinder; the inner cavity of the cylinder is a cylindrical oscillating cavity; the upper end of the inlet nozzle is connected with a high-pressure pipe by external threads arranged on the cylindrical face of the end part of the upper end; the middle of the inlet nozzle is spirally connected with inner ring threads of the adjusting ring by external threads arranged on the outer cylindrical face of the middle; the lower end of the inlet nozzle is spirally screwed into the oscillating cavity of the base; the base is fixedly connected with the adjusting ring and the outlet nozzle respectively by screws, through holes formed in the upper and lower bottom faces of the base, a through hole formed in the adjusting ring and a through hole formed in the outlet nozzle. The high-pressure self-oscillation oscillating impulse jet flow nozzle with the continuous adjustable cavity length has the advantages that aiming at different working pressures, the cavity length of the oscillating cavity can be continuously adjusted by rotating the base, and thus the continuous jet flow is changed into strong impulse jet flow; each part of the nozzle is easily processed, and the replacement is convenient.

The invention discloses an identity authentication method based on a dynamic trusted third party in an open network. By constructing an authentication system structure containing a trust decision-making database, the dynamic trusted third party and an entity joining the network service, the proposal leads an interactive entity not only to obtain necessary information related to identity authentication but also to obtain a trust feedback set of the trusted third party depended by the interactive entity when the interactive entity is carried out identity authentication; and according to the trust feedback set, the entity independently selects a trust decision-making function and calculates the reliability thereof. The proposal consists of four phases of identity authentication information collecting, identity authentication reliability calculating and judging, identity authentication information mutual judging and identity authentication information feed backing. The invention not only realizes dynamic control to the behavior of the trusted third party by the identity authentication entity in the open network, but also improves the reliability of identity authentication by carrying out reliability calculating and judging.

When an organic EL display apparatus enables display of a standard luminance mode and a high luminance mode, it takes long time to reset the gate potential of the OLED drive TFT to a given value in a standard mode. In the reset operation of the gate potential of an OLED drive TFT at the time of writing an image signal, in a standard mode, a precharge current is allowed to flow in the OLED element for a short period before the reset operation to set an initial value of the gate potential of the OLED drive TFT to be close to a supply potential or a reference potential. With the above operation, the variation of the OLED drive TFT gate potential after resetting is reduced. As a result, the light emitting period during one frame can be extended. Also, since a blanking period can be extended, it is possible to measure the characteristic of the OLED element by using the blanking period.

A precoder for an effective channel linking a wireless receiver to a wireless transmitter includes a precoder report and a precoder update report, the effective channel including a propagation channel, transmit filters and receive filters. A structured frequency-selectivity of the effective channel is determined, the structured frequency-selectivity being induced by one or more long term and/or persistent parameters of the effective channel. The precoder update report is generated based on the structured frequency-selectivity. The precoder update report includes frequency-dependent phase compensation which accounts for the structured frequency-selectivity. The precoder report is generated for the effective channel based on channel state information determined for the effective channel. The precoder report and the precoder update report are transmitted to the wireless transmitter. The transmitter determines a transmission operation based on the precoder report and the precoder update report, and transmits data to the wireless receiver in accordance with the transmission operation.
